Product Description

Fitment: BMW E9X / E8X /

These mounts are designed for all BMW E9x and E8x cars with an N5x engine (excludes the M3). They are rebuildable and the polyurethane bushing inserts can be easily swapped out for a different hardness.

These mounts are made from CNC machined 6061-T6 billet aluminum combined with high quality polyurethane. Revshift mounts are the most durable and reliable mounts on the market. To further ensure the strength of our mounts we form the threads with a forming tap which creates denser and stronger threads in the billet aluminum pieces.

The polyurethane compounds that Revshift uses are among the best for automotive use and exceed the material quality of possibly all other automotive polyurethane manufacturers.

Polyurethanes are a group of organic polymers that are normally grouped with rubber. Polyurethanes are elastomers which are stretchy materials. They come from the reaction of diisocyanates, long chain polyols and short chain extenders. This process has proven itself to be a flexible method of producing customised elastomers with adjustable properties.

Polyurethanes achieve hardnesses on a wider range than any other elastomer and exhibit outstanding physical properties such as: abrasion, by far better than steel; tear resistance, superior to these of many other elastomers; resilience; load bearing capabilities. Through the years, their special properties made them indispensable in more and more fields replacing other materials with lower properties.

- Our polyurethane can be tuned to produce polymers of different hardnesses and physical properties to suit the application

- Our polyurethane is elastic and can absorb an enormous amount of trauma without permanently deforming (unlike UHMW and Delrin)
